Joe Kelly

Chicago White Sox

Pitch Repertoire At-A-Glance

Joe Kelly has thrown 13,631 pitches that have been tracked by the PITCHf/x system between 2012 and 2022, including pitches thrown in the MLB Regular Season, the MLB Postseason and Spring Training. In 2022, they have relied primarily on their Curve using a Knuckle Curve grip (88mph) and Sinker (98mph), also mixing in a Change (87mph). He also rarely throws a Fourseam Fastball (98mph).


In 2022, compared to other RHP:
His curve using a knuckle curve grip is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' curves and has primarily 12-6 movement. His sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair and has slight armside run. His change has an obvious armside fade, generates a high number of swings & misses compared to other pitchers' changeups, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. His fourseam fastball (take this with a grain of salt because he's only thrown 3 of them in 2022) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, is blazing fast and has some natural sinking action.
